The participation of women in Brazil's labor market grew 42 percent between 1998 and 2008, according to the Brazilian Institute of Geography and Statistics (IBGE) on Tuesday.
It is also indicated the percentage of girls between 10 and 15 years old in work has decreased from 11.5 percent to 6.4 percent in a decade.
But, still there were 136 million girls working as maids in 2008.
According to IBGE, the percentage of young and elderly women who work in Brazil is higher than in European countries.
But the good news is that in the analyzed period the percentage of women with only one child, whose per capita income is greater than two minimum wages, increased from 33.0 percent to 40.3 percent.
The study reveals an important indicator in terms of racial inequality.
In 2008, two thirds of white youngsters were studying at university, while less than a third of black and brown youngsters were receiving education of that level.
When it comes to college degrees, 14.7 percent of white adults had one in 2008, while the share for black and brown adults was merely 4.7 percent.
